NaClONaClHSO ClOClNaSOHO++ =+++
The product gas, mixed with the by-product chlorine, is stripped from the solution by a current of air and
passed into water. The chlorine dioxide dissolves, and most of the chlorine does not; the latter is absorbed in a
second column containing alkali. Developed by W.H. Rapson at Hooker Chemical Corporation and operated
at Springhill, LA, from 1961.
U.S. Patent 2,863,722.
